Improvement in wagon-brakes



UNITED STATES PATENT Ortrce.

J. H. WILKINSON, OF KIGKAPOO, ILLINOIS.

lM PROVEM'ENT IN WAGON-BRAKES.

Specification forming part of Letters Patent No. 53,2 [0, dated March 13, 1866.

To all whom 'it may concern:

Be it known that I, J. H. WILKINSON, of Kickapoo, in the county of Peoria and State of Illinois, have invented a new and Improved Wagon-Brake; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make anti use the same, reference being had to the accompanying drawings, forming part of this specification, in which I Figure l is a longitudinal vertical section of a wagoxrtruck with my brake applied there- To enable others to understand my in\'ention, I will proceed to describe it.

A designates the bind, and A the forward, wheels of a wagon-truck.

B is a sliding reach, which is secured to the front axle and passes between the transverse bars a a, as shown clearly in Fig. 2.

(J is the stationary reach, which is secured to the hind axle in the usual manner. This extends but a portion of the distance between the two wheels, and the sliding reach rests upon it. Aband, b, is placed over the sliding reach to keep it in place upon the stationary reach 0.

D. is a clip, the lower ends of which are bolted to the stationary reach 0, as shown clearly in Fig. l at c, and passes over the sliding reach B, being also bolted to that, as shown at din Fig. 1. By taking out the bolt d the sliding reach B may be let out, so as to increase the distance between the front and hind wheels, and may be inserted again and secure the parts again in proper position.

E E are the brakes. They are hinged or otherwise secured in a proper manner to the stationary reach U, as shown in Fig. 2, so as to have an up-and-down motion. These brakes are connected to the clip D by rods 0 0, one for each brake, which rods are secured to the clip on each side thereof, and they are also connected to the hind axle by two other rods, ff, which keep the brakesfrom swinging out of place, all of which is shown clearl y in Fig. 2.

The operation is as follows: When the vehicleis drawn along on level ground or uphill the forward pull on'the sliding reach B draws forward the top portion of the clip D, which, through the medium of the rods e 6, draws forward the brakes, and rods ff cause them to swing upward away from the wheels. It will be seen that the brakes are lifted upward from the wheels. Now, so soon as the vehicle commences descending a hill the stationary reach 0 will press forward and throw the lower end of the clip D forward, which causes the upper end to force down the brakes or let them fall against the wheels; and itwill be seen that the harder the hind wheels press forward the harder will the brakes be held against the wheels, and that so soon as this forward pressure of the hind wheels is released the brakes will slacken of their own accord, and thus the brakes act automatically.

I claim as new and desire to secure by Letters Patent 1. The rods 6 c and ff, in combination with the clip D and brakes E E, substantially as shown and described.

2. lhe clip D, in combination with the slidin g reach B and stationary reach 0 and brakes E E, substantially as and for the purpose specispecified.

3. The combination of the sliding reach B, stationary reach G, clip D, brakes E E, rods 6 e andf f, and bind and forward axles of a vehicle, all operating together, substantially as and for the purpose specified.

J. H. WILKINSON.
